儿童偏头痛脑干、视觉诱发电位及经颅多普勒超声的检测

Detection of BAEP, VEP and TCD in children with migraine

目的 为探讨儿童偏头痛发作期和间隙期脑干、视觉通路及血管功能异常。方法 本文采用诱发电位（ＢＡＥＰ，ＶＥＰ） ，经颅多普勒（ＴＣＤ） 检测了３０ 例儿童偏头痛患者。结果 偏头痛发作期ＢＡＥＰ，ＶＥＰ，ＴＣＤ 异常率分别为４７ ％ ，７７ ％ 和８３％ 。ＢＡＥＰⅠ，Ⅲ，Ⅴ波潜伏期及Ⅲ～Ⅴ峰间期延长。ＶＥＰ双侧偏头痛患者Ｐ１００ 潜伏期延长，波幅（Ｎ７５ ～Ｐ１００） 明显增高。ＴＣＤ发现ＭＣＡ，ＡＣＡ在头痛侧平均血流速度明显增快。结论 上述结果表明偏头痛患儿有视觉和脑干传导功能障碍及血管功能改变。

Objective To study the changes of brainstem, visual passage and vascular function in children with migraine during attack. Methods BAEP,VEP and TCD were detected for 30 children with migraine. Results During attack, 47% of BAEP, 77% of VEP and 83% of TCD were found abnormal. The period of wave Ⅰ,Ⅲ,Ⅴ and Ⅲ～Ⅴ in BAEP was prolonged. The latency of P 100 in VEP was prolonged and amplitude was significantly higher. The MCA and ACA of the mean blood velocity in TCD at the headache side was apparently faster. Conclusions These indicated the disturbance of functions such as vision and brain stem in patients with migraine. The blood spasm existed.
